Abstract
Benzoylamides of the general formula (I) are described as herbicides. In this formula (I), B, X1 and X2 represent N, O or S(O)n. R, Ra, Rb and Rx represent radicals such as hydrogen, halogen, (C1-C6)-alkyl, halo-(C1-C6)-alkyl, (C1-C6)-alkyloxy and cyano.

A compound of formula (II)
- in which the symbols and indices have the following meanings:
- L represents chlorine, methoxy, ethoxy or hydroxy,
- X1, X2 independently of one another each represent O or S(O)n, where X1 and X2 are not simultaneously O or S(O)n, wherein n represents 0, 1, or 2,
- R′ represents SO2Me, SO2Et, trifluoromethyl, difluoromethyl or pentafluoroethyl,
- Ra, Rb independently of one another each represent hydrogen, fluorine, chlorine, methyl, ethyl, trifluoromethyl, difluoromethyl, methoxy, ethoxy, methylthio, ethylthio, cyano, or
- Ra and Rb together with the carbon atom to which they are attached form a carbonyl or a thiocarbonyl group.
